If you tan to hide acne on black skin, nothing will be different (unless you are using skin lighteners or benzoyl peroxide, in which case exposure to the sun may cause the formation of black spots on your skin, in addition to any blemishes that may be on your skin).
Applets are designed to be embedded within an HTML page. When a user views an HTML page that contains an applet, the code for the applet is downloaded to the user's machine. A JVM is required to view an applet. The JVM can be either a plug-in of the Web browser or a separate runtime environment.
A program designed to be executed from within another application. Unlike an application, applets cannot be executed directly from the operating system. With the growing popularity of OLE(object linking and embedding), applets are becoming more prevalent. A well-designed applet can be invoked from many different applications. Web browsers, which are often equipped with Java virtual machines, can interpret applets from Web servers. Because applets are small in files size, cross-platform compatible, and highly secure (can't be used to access users' hard drives), they are ideal for small Internet applications accessible from a browser.
